ZX Spectrum FROM HELL - FINAL episode - Part 4

Zx Spectrum repairs don't get much more extreme than this! The FINAL episode of this repair saga, and I can't imagine ever fixing a more broken 48k ZX Spectrum! Upper ram reinstalled. Lower ram faults. More logic faults. Even new keyboard faults. It's the gift that keeps on giving! And lots of repairs too!
